I need a detailed step-by-step solution for the following calculus question:
1. Find the derivative of f(x) = (3x + 5x – 2) / (x + 1)
2. Find the indefinite integral of f(x) = x + 2x – 5x + 7
Please explain each step clearly, especially the quotient rule and integration by parts if used. Also show the final answer.
I have an exam tomorrow, so I need clear explanations.

I am currently studying differential calculus and need help applying the chain rule. Specifically, I am struggling to differentiate the composite function f(x) = sin(3x^2 + 5) . Could you please provide a step-by-step breakdown of how to identify the inner and outer functions, and explain how the chain rule formula frac{dy}{dx} = frac{dy}{du} cdot frac{du}{dx} is applied to reach the final derivative?
Calculus is about change and ation. You use it to model real systems. Core idea 1: Derivatives frac{d}{dx}x^n = nx^{n-1}What it means: Rate of change at a point Slope of a curve Where you use it: Physics: velocity and acceleration Engineer
. Condition for an Irrotational FieldA vector field is irrotational if its curl is zero: (nabla times vec{F} = vec{0}).2. Calculating the CurlThe curl is calculated using the following determinant:(nabla times vec{F}=left|begin{matrix}^{i}&^{j}&^{k}\ frac{partial }{partial x}&frac{partial }{partial y}&frac{partial }{partial z}\ axy+z^{3}&3x^{2}-z&bxz^{2}-yend{matrix}right|)Expanding this, we solve for each component:(^{i}) component:(frac{partial}{partial y}(bxz^2 – y) – frac{partial}{partial z}(3x^2 – z) = (-1) – (-1) = 0)(^{j}) component:(-left[frac{partial }{partial x}(bxz^{2}-y)-frac{partial }{partial z}(axy+z^{3})right]=-left[bz^{2}-3z^{2}right]=-z^{2}(b-3))(^{k}) component:(frac{partial}{partial x}(3x^2 – z) – frac{partial}{partial y}(axy + z^3) = 6x – ax = x(6 – a))3. Solving for constantsFor (nabla times vec{F} = vec{0}) to hold true, each component must be zero:From the (^{j}) component:(-z^2(b – 3) = 0 implies b – 3 = 0 implies mathbf{b = 3})From the (^{k}) component:(x(6 – a) = 0 implies 6 – a = 0 implies mathbf{a = 6})Final AnswerThe constants are:(a = 6) and (b = 3) Dive deeper in AI Mode Footer linksResults are personalised-Try without personalisation
